The document describes the design and development of a wheelchair that can convert into a stretcher. Three undergraduate students and a professor designed the device using PRO-E software. Their goals were to create a more affordable and adjustable wheelchair that eliminates issues with transferring patients between wheelchairs and stretchers. Key features of the design include easy conversion between the wheelchair and stretcher modes using mechanisms. Analysis in the software focused on strength, weight, and stability. The design was meant to improve patient handling and comfort while reducing space needs and risks of damage during transfers.

Abstract: Now a day common scenario observed in the
medical field that person suffers from manymore diseasesand
some kind of diseases required more care like to paralyzed
patients. Wheelchair is a devise that is used to improve the
accessibility of mobility challenged persons. This study will
illustrates the new fully comfortable design for physically
handicapped person comparative to available designs in
general use. The objective of this study is to design the
convertible wheelchair to stretcher easily by means of design
software and obtain the idea in actual practice.
Key Words: PRO-E, Wheelchair, Stretcher.
1. INTRODUCTION
The terminology of the wheelchair has defined already in
various types. Wheelchairsareusedbyphysicallychallenged
people i.e. people who have difficulty in sitting and walking
often make use of wheelchair. The reason of the study to
design, development and analysis of new wheelchair which
is suitable for various range of users and which are easily
adjusted and obtain at very low cost than already exists
wheelchair. Analyzing the market survey it can provide
alternative option by eliminating high cost, less adjustable
wheelchair for rehabilitation. Taking all existing
considerations related to wheelchair in account prepared a
model design with different base frame model using PRO-E
software on the basis of user’s data consideringaveragedata
among it. The assessmentof wheelchairdesignisperforming
by computer analysis software which can focus on
performance features such as static strength, weight and
stability of it.
1.1 Project Concept
Generally the patients in the hospitals is restricted to be on
bed or completely in wheelchair and if patienttakentoother
places for various tests then wheelchair in the hospitals are
not converted into the stretcher and hence main aim of this
section to developed the chair that can obtain the stretcher
form by various mechanism and it is the idea to form a
design of wheelchair that can be also convert into the
stretcher which will lead to occupy place of chair as well as
stretcher and we don’t need to move patient from chair.
1.2 Handling Problems
Transferring patient from the one place to another place in
hospitals is most common problems for all working
members at there. When the patient tends to transfer on the
same floor it develops various stresses and pain in body of
both patient as well as nursing staff. Various accessories
transportation is also more difficult when patient is in
serious condition in manual handling. Hence the above
problems can be eliminated by developing new Wheelchair
cum Stretcher to handle the patients.
2. Design of Model
2.1 Design of Wheelchair and Stretcher
Taking in account all the considerationsrelatedto physically
handicapped people our design provide simple and cost
effective construction. On the basis of marketing survey and
all problems of complexity and economy, we design new
product which is user-friendly and automated. Proper
material selection improves product life and cost
effectiveness by evaluating its analysis. All design is of
wheelchair as well as stretcher is created in PRO-E software
by studying and evaluating all ergonomics of wheelchair as
per medical fields review. The actual model is showninfig,1.
Since the concept of this project is that wheelchairturnsinto
stretcher form also and hence the stretcher form design is
also evaluated and shown in fig.2.

3. Advantages
1. Aim to convert easily from wheelchair to
stretcher and stretcher to wheelchair.
2. There is no need of special training.
3. Since operation is smooth so handling of
patient is more secured.
4. Comfort level of system as well as patient is
increased.
5. Space requirement is minimized.
6. Predicted damages are reduced for patient
while handling.
4. Conclusion
With the help of software based design we conclude all
possible ideas to the model before implement it in actual
system. The main purpose of this study to enhance the
design of wheelchair and stretcher, showing sit tilting
mechanism by means of linear actuator system which leads
to optional source for physically challenged. The aim to
provide a better solution for patient handling to those
hospitals having limitations for use of fully automated bed
or wheelchair cum stretcher.
